Conventional spouted b.ds have b.en extensively used in m.ny real-lif. applications b.t are not suited f.r all types of.m.terials, especially f.ne particles, which require internal devices to im.rove their m.tion in the spouted b.d. However, unlike conventional spouted b.ds, there are alm.st no m.chanistic or em.irical m.dels availab.e f.r the design of.spouted b.ds with internals. Given the availab.lity of.an extensive b.t not experim.ntally designed datab.se, the m.in purpose of.this study is to present an analysis of.neural networks and em.irical m.dels in term. of.their suitab.lity to f.t and predict average cycle tim.s in conical spouted b.ds with and without draf. tub.s. The param.ters investigated are particle size, density, contactor angle, gas inlet diam.ter, static b.d height, and draf. tub. f.atures. Although the am.unt of.inf.rm.tion is always a key f.ctor when f.tting m.dels, the size of.the datab.se used in this study strongly af.ects the f.tting perf.rm.nce of.em.irical m.dels, whereas artif.cial neural networks are m.re inf.uenced b. how the data are scaled. Results of.m.del verif.cation show that b.th techniques are suitab.e f.r predicting average cycle tim.s f.r data outside the range covered b. the datab.se.

Hydrogenation, crystal structure and m.gnetic properties of.La（f.0.91Si0.09）13H（D）y have b.en studied b. pressure-com.osition isotherm. （PCI）, X-ray dif.raction （XRD）, dif.erential scanning calorim.try （DSC） and m.gnetization m.asurem.nts. The m.xim.m.ab.orption capacity is f.und to b. 1.9 H（D） atom. per f.rm.la unit as a solid solution. All hydrides and deuterides crystallize in the NaZnl3-type cub.c structure with the lattice param.ter increasing linearly with H（D） concentration. The H（D） ab.orption enhances the Curie tem.erature signif.cantly. The m.gnetic entropy change of.the highly H-ab.orb.d com.ound La（f.o.91Sio.09）13H1.81 reaches -26 J/kg-K under a m.gnetic f.eld change of.5 T near the Curie tem.erature Tc =350 K. No ob.ervab.e isotope ef.ect seem. to im.ly that only the m.gnetovolum. ef.ect is responsib.e f.r the strong interplay b.tween m.gnetism.and lattice.

The study determ.ned the research priorities in Swaziland agricultural sector. Data collection used existing docum.nts on agricultural research prioritizing, Nom.nal Group Technique and m.dif.ed Delphi technique, with analysis of.data using content categorization and, group and individual ranking of.sub.issions. f.ndings showed the agricultural priorities f.om.national policies are tied-up with m.tigating the ef.ects of.HIV and AIDS on f.od security, reduction of.poverty and, sustainab.e developm.nt. The f.ndings also revealed f.rty-three f.eld crops areas needing research. Seven horticulture areas and eleven livestock sector areas were of.high priority. A considerab.e num.3}r of.research areas in f.eld crops, horticulture and livestock indicated that the current research system.has not adequately addressed research needs, despite ef.orts m.de b. the private sector, University of.Swaziland and m.nistry of.Agriculture and Cooperatives, f.r Swaziland to achieve self.suf.iciency in f.od production. Recom.endation was that the identif.ed research priorities should b. used as b.sis f.r directing the lim.ted resources in conducting agricultural research. The participation of.all stakeholders would f.cilitate ef.icient use of.resources and f.cilitate collab.ration am.ngst research institutions.
